DETERMINATION THE EFFECTS OF DUTY CYCLE AND SWITCHING FREQUENCY ON EFFICIENCY OF BOOST CONVERTER FOR FIXED LOAD APPLICATIONS
Abstract
Recent years, power converters have been a significant part of daily
applications such as PV systems, wind turbines, electrical vehicle chargers and
adapters. Due to the arising energy demand and the energy restrictions of the
environment, energy efficiency of power converters become crucial. Energy
efficiency of these converters can be enhanced using appropriate converter
topology, effective modeling and control algorithms. Therefore, in this study,
we aim to model and analyze the power losses of boost converter to determine
best usage interval in terms of duty cycle and switching frequency. The
proposed model is designed by using Simulink and the results in terms of
efficiency and power losses are obtained and analyzed in MATLAB. The results of
this study demonstrate that, appropriate selection of duty cycle and switching
frequency provide lower power losses and thus higher efficiencies.
